Why not go with 3 PSUs? For $60 you can get something like Corsair CX500, which will easily power a single ant, even an overclocked one.

Cables, and How would i go about setting each one up? Im running these in my garage which only has two outlets (2 plugs, not two sets of two) but that's it, so I have the whole circuit to myself xD. I don't really want 1500w running through a power strip..... I also need the other plug for ethernet over power bridges. SO yeah, how should I go about doing this?

A power strip rated at 15A+ will run 1500W no problem, and it costs less than $10. Besides, you will only need 3x400W=1200W to power the miners.

You can go for a gold rated PSU to save 5-10% of power consumption, say Rosewill CAPSTONE-450 450W Continuous @ 50°C for $60.

If you are set on using a single PSU, go for this one Rosewill LIGHTNING-1300 1300W Continuous @ 50°C for $240, it's also modular, so even less cables.

cx 750m (two of them) seems to be the most cost effective option. Also thanks for calming me about the power strip, time to find a decent power strip. Do you think a UPS is needed?

Just wanted to chime in with my 0.02BTC. We're running 8 Ants on 2 server PSUs. Running a 10ga wire with a female tab connector to 6x 14ga wires that go into the screw terminals. Red=12v, Black=ground. 1 of each for each Ant, 16 wires total, and really easy to set up. The hardest part was splicing, threading, twisting, and soldering the 6x 14ga wires into a single 10ga wire, but that wasn't bad.

We soldered the wires for the 3 fans together, with a 12v and ground lead coming out, and soldered those to 2 random tabs, and now our fans are all set. Each PSU is using ~80% of it's rated max,and they're running cool and stable. Total for the 2 PSUs, 6 fans, and all 8 Ants (with both the main fan and second added fan @ 100%) is 16.5A @ 208V. Temps are averaging in the high 30s, OC'd to 393 (~200GH/s).

You are using the wrong power supply. It is a good clue that the supply is crap when nobody publishes the specs. I finally found them on an ebay listing. Dual 12v rails. One for the processor, one for the rest of the system. You have 380 watts worth of 12v to run your miner outta that craptastic supply.

Don't really care about lifespan, more really about stability. I will look into getting a higher wattage, but i really wanna get 2 antminers s1 and the accessories needed for $1500.

go for a 1200watt maxing out the psu still reduces life span and good to have a buffer zone of a 100watt or so. my 2bits worth.

So you guys think its feasible to run 3 of these at stock clocks off a xfx 1050w pro series? I single this one out, since this is guaranteed for that delivery at 50 degrees Celsius, so it should output higher wattages at lower temps.

If this is the one you had, it popped because it could provide just 16 or 18 Amps via its dual PCI-E connectors, while Antminer requires at least 30 Amps. When shopping for a PSU either select a tested and recommended one, or look for a PSU with a single rail 12V which provides at least 40 Amps, and preferably with separate PCI-E connectors, not dual ones.

I was running one unit off a Dell N750P PSU. The fan noise was a killer though, so today I switched to an IBM DPS-2500BB A PSU, cooled with two 3000rpm 120mm fans I strapped on the side of it. At over 200 ampere at 12v it is a total overkill for one antminer so I'll try hooking 3 more units to it tomorrow.

EDIT : if sidehack comes though with his mod thingy and I will be able to tune the fan speed on the Dell PSU, it'll be perfect, as I really like these units. Very compact.

The fan noise on the dell psu's are quite tolerable when you utilize the 50% fan speed pin.

Ye that psu is bad boy quality.

why only 4 pcie cables it offers upto 8, Is it to offload from the 12v rail?

Because to give you eight the cables have two connectors each and I only want to use one per blade

most comfortable option is at least 750 for 1, 1200 for 2, overclocked. they dont use all that power but its more the cable size, they tend too get warm with the lesser psu. the 1500 watts have good thick cables you dont feel anything.

i measures 490 watts overclocked at the wall per unit.

i have 2 ants oc-running on a 1kW bequiet powerzone 1000 with cool cables and 810W at wall

are they overclocked also?

You might want a dummy plug for the ATX plug. I thinks someone mentioned this happening when the jumper wire shorted.

It sounds like the power supply is not high enough rated you might want to concider using gold rated or platinum. I have a 750w corsair and unit overclocked and shorting the 24pin with a strong enough wire and each ant is running perfectly fine so far.

If you are using a basics none branded or generic and not modeler power supply or anything under gold rated you will get problems. Also make sure your using 1 pci-e cable per 6pin connector and not using 1 with the splatter on it to connect to both modules. I use 1 for each module so total use is 2 pci-e cables connected up.

yep absolutely right. Cheap Psu it was fine in my bitburner fury es for a few month But they don't consume as much. I'm using silverstone strider 1500watt and some corsair 650watt.

with a killawatt check, my s1 uses 420@stock and 490@200ghs 400mhz. put 3 on a 1350watt psu, which claims 1500 watt peak, was running fine on one batch but on another on of the s1 switches on and off, i assumed it was not getting enough power, underclocked it was fine.

was told that running the psu at peak reduces its life by 40% and may even damage it.

Apparently a 530W psu can run a standard (not over clocked) S1. So you'll need 2.12kW to run 4 (530*4).

thats because all pc psu have a max load for 3.3 + 5V + Antivoltages and another max for the 12V rails wich is then combined to the official watts on the box. while high power "gamer" supplies tend to deliver up to 95% of their stated power on 12V

so you need a "reserve" on a 500w one but can run 3 ants on a 1200w one instead 1500

You should be able to safely run 2 Ants on a 1000W PSU, or 3 ants on a 1300W PSU.

I would not try to run 4 Ants on a single PSU. It's difficult and expensive to find a single PSU that can run over 1600W.

Each Ant requires 2 dedicated PCI-E cables to safely run.

I'm running 2 ants per AX860 PSU and 3 ants per EVGA G2 1300W PSU

i think you should use Corsair ax860(comes with 7 years warranty) platinum it has a 93% eff. on 230v i used to have 2 antminers @ 180ghash stock clock and 25 usb sticks with no problem. best psu you can get otherwise you should go for the Evga Supernova 1300 Gold(10 years warranty) where u can run 3 ants on.

The 500w measurement is completely false, was done w/ a shitty PSU. At the wall w/ a 80+ GOLD @ 120v, I see about 1w / mhz, so 400mhz is about 400w! Take 10% off that and these use roughly 360w @ 400mhz, on the PSU itself.

My bad then. Sorry for the false info. At least I learnt something new today

Agreed, all of my Ants use less than 400W at the wall running at 200GH/s using a good quality, Gold PSU.

You should be able to safely run 2 Ants on a 1000W PSU, or 3 ants on a 1300W PSU.

I would not try to run 4 Ants on a single PSU. It's difficult and expensive to find a single PSU that can run over 1600W.

Each Ant requires 2 dedicated PCI-E cables to safely run.
